CROSS-REFERENCE TO RELATED APPLICATION(S)

This application claims the benefits of U.S. Provisional ApplicationSer. No. 62/716,393, entitled “COLLISION OF PUCCH CONSIDERING MULTI-SLOTOPERATION” and filed on Aug. 9, 2018, which is expressly incorporated byreference herein in their entirety.

BACKGROUND Field

The present disclosure relates generally to communication systems, andmore particularly, to techniques of transmitting multiple multi-slotuplink control channels by a user equipment (UE).

Background

The statements in this section merely provide background informationrelated to the present disclosure and may not constitute prior art.

Wireless communication systems are widely deployed to provide varioustelecommunication services such as telephony, video, data, messaging,and broadcasts. Typical wireless communication systems may employmultiple-access technologies capable of supporting communication withmultiple users by sharing available system resources. Examples of suchmultiple-access technologies include code division multiple access(CDMA) systems, time division multiple access (TDMA) systems, frequencydivision multiple access (FDMA) systems, orthogonal frequency divisionmultiple access (OFDMA) systems, single-carrier frequency divisionmultiple access (SC-FDMA) systems, and time division synchronous codedivision multiple access (TD-SCDMA) systems.

These multiple access technologies have been adopted in varioustelecommunication standards to provide a common protocol that enablesdifferent wireless devices to communicate on a municipal, national,regional, and even global level. An example telecommunication standardis 5G New Radio (NR). 5G NR is part of a continuous mobile broadbandevolution promulgated by Third Generation Partnership Project (3GPP) tomeet new requirements associated with latency, reliability, security,scalability (e.g., with Internet of Things (IoT)), and otherrequirements. Some aspects of 5G NR may be based on the 4G Long TermEvolution (LTE) standard. There exists a need for further improvementsin 5G NR technology. These improvements may also be applicable to othermulti-access technologies and the telecommunication standards thatemploy these technologies.

FIG. 1 is a diagram illustrating an example of a wireless communicationssystem and an access network 100. The wireless communications system(also referred to as a wireless wide area network (WWAN)) includes basestations 102, UEs 104, and a core network 160. The base stations 102 mayinclude macro cells (high power cellular base station) and/or smallcells (low power cellular base station). The macro cells include basestations. The small cells include femtocells, picocells, and microcells.

The base stations 102 (collectively referred to as Evolved UniversalMobile Telecommunications System (UMTS) Terrestrial Radio Access Network(E-UTRAN)) interface with the core network 160 through backhaul links132 (e.g., S1 interface). In addition to other functions, the basestations 102 may perform one or more of the following functions:transfer of user data, radio channel ciphering and deciphering,integrity protection, header compression, mobility control functions(e.g., handover, dual connectivity), inter-cell interferencecoordination, connection setup and release, load balancing, distributionfor non-access stratum (NAS) messages, NAS node selection,synchronization, radio access network (RAN) sharing, multimediabroadcast multicast service (MBMS), subscriber and equipment trace, RANinformation management (RIM), paging, positioning, and delivery ofwarning messages. The base stations 102 may communicate directly orindirectly (e.g., through the core network 160) with each other overbackhaul links 134 (e.g., X2 interface). The backhaul links 134 may bewired or wireless.

The base stations 102 may wirelessly communicate with the UEs 104. Eachof the base stations 102 may provide communication coverage for arespective geographic coverage area 110. There may be overlappinggeographic coverage areas 110. For example, the small cell 102′ may havea coverage area 110′ that overlaps the coverage area 110 of one or moremacro base stations 102. A network that includes both small cell andmacro cells may be known as a heterogeneous network. A heterogeneousnetwork may also include Home Evolved Node Bs (eNBs) (HeNBs), which mayprovide service to a restricted group known as a closed subscriber group(CSG). The communication links 120 between the base stations 102 and theUEs 104 may include uplink (UL) (also referred to as reverse link)transmissions from a UE 104 to a base station 102 and/or downlink (DL)(also referred to as forward link) transmissions from a base station 102to a UE 104. The communication links 120 may use multiple-input andmultiple-output (MIMO) antenna technology, including spatialmultiplexing, beamforming, and/or transmit diversity. The communicationlinks may be through one or more carriers. The base stations 102/UEs 104may use spectrum up to Y MHz (e.g., 5, 10, 15, 20, 100 MHz) bandwidthper carrier allocated in a carrier aggregation of up to a total of YxMHz (x component carriers) used for transmission in each direction. Thecarriers may or may not be adjacent to each other. Allocation ofcarriers may be asymmetric with respect to DL and UL (e.g., more or lesscarriers may be allocated for DL than for UL). The component carriersmay include a primary component carrier and one or more secondarycomponent carriers. A primary component carrier may be referred to as aprimary cell (PCell) and a secondary component carrier may be referredto as a secondary cell (SCell).

The wireless communications system may further include a Wi-Fi accesspoint (AP) 150 in communication with Wi-Fi stations (STAs) 152 viacommunication links 154 in a 5 GHz unlicensed frequency spectrum. Whencommunicating in an unlicensed frequency spectrum, the STAs 152/AP 150may perform a clear channel assessment (CCA) prior to communicating inorder to determine whether the channel is available.

The small cell 102′ may operate in a licensed and/or an unlicensedfrequency spectrum. When operating in an unlicensed frequency spectrum,the small cell 102′ may employ NR and use the same 5 GHz unlicensedfrequency spectrum as used by the Wi-Fi AP 150. The small cell 102′,employing NR in an unlicensed frequency spectrum, may boost coverage toand/or increase capacity of the access network.

The gNodeB (gNB) 180 may operate in millimeter wave (mmW) frequenciesand/or near mmW frequencies in communication with the UE 104. When thegNB 180 operates in mmW or near mmW frequencies, the gNB 180 may bereferred to as an mmW base station. Extremely high frequency (EHF) ispart of the RF in the electromagnetic spectrum. EHF has a range of 30GHz to 300 GHz and a wavelength between 1 millimeter and 10 millimeters.Radio waves in the band may be referred to as a millimeter wave. NearmmW may extend down to a frequency of 3 GHz with a wavelength of 100millimeters. The super high frequency (SHF) band extends between 3 GHzand 30 GHz, also referred to as centimeter wave. Communications usingthe mmW/near mmW radio frequency band has extremely high path loss and ashort range. The mmW base station 180 may utilize beamforming 184 withthe UE 104 to compensate for the extremely high path loss and shortrange.

The core network 160 may include a Mobility Management Entity (MME) 162,other MMEs 164, a Serving Gateway 166, a Multimedia Broadcast MulticastService (MBMS) Gateway 168, a Broadcast Multicast Service Center (BM-SC)170, and a Packet Data Network (PDN) Gateway 172. The MME 162 may be incommunication with a Home Subscriber Server (HSS) 174. The MME 162 isthe control node that processes the signaling between the UEs 104 andthe core network 160. Generally, the MME 162 provides bearer andconnection management. All user Internet protocol (IP) packets aretransferred through the Serving Gateway 166, which itself is connectedto the PDN Gateway 172. The PDN Gateway 172 provides UE IP addressallocation as well as other functions. The PDN Gateway 172 and the BM-SC170 are connected to the IP Services 176. The IP Services 176 mayinclude the Internet, an intranet, an IP Multimedia Subsystem (IMS), aPS Streaming Service (PSS), and/or other IP services. The BM-SC 170 mayprovide functions for MBMS user service provisioning and delivery. TheBM-SC 170 may serve as an entry point for content provider MBMStransmission, may be used to authorize and initiate MBMS Bearer Serviceswithin a public land mobile network (PLMN), and may be used to scheduleMBMS transmissions. The MBMS Gateway 168 may be used to distribute MBMStraffic to the base stations 102 belonging to a Multicast BroadcastSingle Frequency Network (MBSFN) area broadcasting a particular service,and may be responsible for session management (start/stop) and forcollecting eMBMS related charging information.

The base station may also be referred to as a gNB, Node B, evolved NodeB (eNB), an access point, a base transceiver station, a radio basestation, a radio transceiver, a transceiver function, a basic serviceset (BSS), an extended service set (ESS), or some other suitableterminology. The base station 102 provides an access point to the corenetwork 160 for a UE 104. Examples of UEs 104 include a cellular phone,a smart phone, a session initiation protocol (SIP) phone, a laptop, apersonal digital assistant (PDA), a satellite radio, a globalpositioning system, a multimedia device, a video device, a digital audioplayer (e.g., MP3 player), a camera, a game console, a tablet, a smartdevice, a wearable device, a vehicle, an electric meter, a gas pump, atoaster, or any other similar functioning device. Some of the UEs 104may be referred to as IoT devices (e.g., parking meter, gas pump,toaster, vehicles, etc.). The UE 104 may also be referred to as astation, a mobile station, a subscriber station, a mobile unit, asubscriber unit, a wireless unit, a remote unit, a mobile device, awireless device, a wireless communications device, a remote device, amobile subscriber station, an access terminal, a mobile terminal, awireless terminal, a remote terminal, a handset, a user agent, a mobileclient, a client, or some other suitable terminology.

FIG. 2 is a block diagram of a base station 210 in communication with aUE 250 in an access network. In the DL, IP packets from the core network160 may be provided to a controller/processor 275. Thecontroller/processor 275 implements layer 3 and layer 2 functionality.Layer 3 includes a radio resource control (RRC) layer, and layer 2includes a packet data convergence protocol (PDCP) layer, a radio linkcontrol (RLC) layer, and a medium access control (MAC) layer. Thecontroller/processor 275 provides RRC layer functionality associatedwith broadcasting of system information (e.g., MIB, SIBs), RRCconnection control (e.g., RRC connection paging, RRC connectionestablishment, RRC connection modification, and RRC connection release),inter radio access technology (RAT) mobility, and measurementconfiguration for UE measurement reporting; PDCP layer functionalityassociated with header compression/decompression, security (ciphering,deciphering, integrity protection, integrity verification), and handoversupport functions; RLC layer functionality associated with the transferof upper layer packet data units (PDUs), error correction through ARQ,concatenation, segmentation, and reassembly of RLC service data units(SDUs), re-segmentation of RLC data PDUs, and reordering of RLC dataPDUs; and MAC layer functionality associated with mapping betweenlogical channels and transport channels, multiplexing of MAC SDUs ontotransport blocks (TBs), demultiplexing of MAC SDUs from TBs, schedulinginformation reporting, error correction through HARQ, priority handling,and logical channel prioritization.

The transmit (TX) processor 216 and the receive (RX) processor 270implement layer 1 functionality associated with various signalprocessing functions. Layer 1, which includes a physical (PHY) layer,may include error detection on the transport channels, forward errorcorrection (FEC) coding/decoding of the transport channels,interleaving, rate matching, mapping onto physical channels,modulation/demodulation of physical channels, and MIMO antennaprocessing. The TX processor 216 handles mapping to signalconstellations based on various modulation schemes (e.g., binaryphase-shift keying (BPSK), quadrature phase-shift keying (QPSK),M-phase-shift keying (M-PSK), M-quadrature amplitude modulation(M-QAM)). The coded and modulated symbols may then be split intoparallel streams. Each stream may then be mapped to an OFDM subcarrier,multiplexed with a reference signal (e.g., pilot) in the time and/orfrequency domain, and then combined together using an Inverse FastFourier Transform (IFFT) to produce a physical channel carrying a timedomain OFDM symbol stream. The OFDM stream is spatially precoded toproduce multiple spatial streams. Channel estimates from a channelestimator 274 may be used to determine the coding and modulation scheme,as well as for spatial processing. The channel estimate may be derivedfrom a reference signal and/or channel condition feedback transmitted bythe UE 250. Each spatial stream may then be provided to a differentantenna 220 via a separate transmitter 218TX. Each transmitter 218TX maymodulate an RF carrier with a respective spatial stream fortransmission.

At the UE 250, each receiver 254RX receives a signal through itsrespective antenna 252. Each receiver 254RX recovers informationmodulated onto an RF carrier and provides the information to the receive(RX) processor 256. The TX processor 268 and the RX processor 256implement layer 1 functionality associated with various signalprocessing functions. The RX processor 256 may perform spatialprocessing on the information to recover any spatial streams destinedfor the UE 250. If multiple spatial streams are destined for the UE 250,they may be combined by the RX processor 256 into a single OFDM symbolstream. The RX processor 256 then converts the OFDM symbol stream fromthe time-domain to the frequency domain using a Fast Fourier Transform(FFT). The frequency domain signal comprises a separate OFDM symbolstream for each subcarrier of the OFDM signal. The symbols on eachsubcarrier, and the reference signal, are recovered and demodulated bydetermining the most likely signal constellation points transmitted bythe base station 210. These soft decisions may be based on channelestimates computed by the channel estimator 258. The soft decisions arethen decoded and deinterleaved to recover the data and control signalsthat were originally transmitted by the base station 210 on the physicalchannel. The data and control signals are then provided to thecontroller/processor 259, which implements layer 3 and layer 2functionality.

The controller/processor 259 can be associated with a memory 260 thatstores program codes and data. The memory 260 may be referred to as acomputer-readable medium. In the UL, the controller/processor 259provides demultiplexing between transport and logical channels, packetreassembly, deciphering, header decompression, and control signalprocessing to recover IP packets from the core network 160. Thecontroller/processor 259 is also responsible for error detection usingan ACK and/or NACK protocol to support HARQ operations.

Similar to the functionality described in connection with the DLtransmission by the base station 210, the controller/processor 259provides RRC layer functionality associated with system information(e.g., MIB, SIBs) acquisition, RRC connections, and measurementreporting; PDCP layer functionality associated with headercompression/decompression, and security (ciphering, deciphering,integrity protection, integrity verification); RLC layer functionalityassociated with the transfer of upper layer PDUs, error correctionthrough ARQ, concatenation, segmentation, and reassembly of RLC SDUs,re-segmentation of RLC data PDUs, and reordering of RLC data PDUs; andMAC layer functionality associated with mapping between logical channelsand transport channels, multiplexing of MAC SDUs onto TBs,demultiplexing of MAC SDUs from TBs, scheduling information reporting,error correction through HARQ, priority handling, and logical channelprioritization.

Channel estimates derived by a channel estimator 258 from a referencesignal or feedback transmitted by the base station 210 may be used bythe TX processor 268 to select the appropriate coding and modulationschemes, and to facilitate spatial processing. The spatial streamsgenerated by the TX processor 268 may be provided to different antenna252 via separate transmitters 254TX. Each transmitter 254TX may modulatean RF carrier with a respective spatial stream for transmission. The ULtransmission is processed at the base station 210 in a manner similar tothat described in connection with the receiver function at the UE 250.Each receiver 218RX receives a signal through its respective antenna220. Each receiver 218RX recovers information modulated onto an RFcarrier and provides the information to a RX processor 270.

The controller/processor 275 can be associated with a memory 276 thatstores program codes and data. The memory 276 may be referred to as acomputer-readable medium. In the UL, the controller/processor 275provides demultiplexing between transport and logical channels, packetreassembly, deciphering, header decompression, control signal processingto recover IP packets from the UE 250. IP packets from thecontroller/processor 275 may be provided to the core network 160. Thecontroller/processor 275 is also responsible for error detection usingan ACK and/or NACK protocol to support HARQ operations.

New radio (NR) may refer to radios configured to operate according to anew air interface (e.g., other than Orthogonal Frequency DivisionalMultiple Access (OFDMA)-based air interfaces) or fixed transport layer(e.g., other than Internet Protocol (IP)). NR may utilize OFDM with acyclic prefix (CP) on the uplink and downlink and may include supportfor half-duplex operation using time division duplexing (TDD). NR mayinclude Enhanced Mobile Broadband (eMBB) service targeting widebandwidth (e.g. 80 MHz beyond), millimeter wave (mmW) targeting highcarrier frequency (e.g. 60 GHz), massive MTC (mMTC) targetingnon-backward compatible MTC techniques, and/or mission criticaltargeting ultra-reliable low latency communications (URLLC) service.

A single component carrier bandwidth of 100 MHZ may be supported. In oneexample, NR resource blocks (RBs) may span 12 sub-carriers with asub-carrier bandwidth of 60 kHz over a 0.125 ms duration or a bandwidthof 15 kHz over a 0.5 ms duration. Each radio frame may consist of 20 or80 subframes (or NR slots) with a length of 10 ms. Each subframe mayindicate a link direction (i.e., DL or UL) for data transmission and thelink direction for each subframe may be dynamically switched. Eachsubframe may include DL/UL data as well as DL/UL control data. UL and DLsubframes for NR may be as described in more detail below with respectto FIGS. 5 and 6.

The NR RAN may include a central unit (CU) and distributed units (DUs).A NR BS (e.g., gNB, 5G Node B, Node B, transmission reception point(TRP), access point (AP)) may correspond to one or multiple BSs. NRcells can be configured as access cells (ACells) or data only cells(DCells). For example, the RAN (e.g., a central unit or distributedunit) can configure the cells. DCells may be cells used for carrieraggregation or dual connectivity and may not be used for initial access,cell selection/reselection, or handover. In some cases, DCells may nottransmit synchronization signals (SS) in some cases DCells may transmitSS. NR BSs may transmit downlink signals to UEs indicating the celltype. Based on the cell type indication, the UE may communicate with theNR BS. For example, the UE may determine NR BSs to consider for cellselection, access, handover, and/or measurement based on the indicatedcell type.

FIG. 3 illustrates an example logical architecture 300 of a distributedRAN, according to aspects of the present disclosure. A 5G access node306 may include an access node controller (ANC) 302. The ANC may be acentral unit (CU) of the distributed RAN 300. The backhaul interface tothe next generation core network (NG-CN) 304 may terminate at the ANC.The backhaul interface to neighboring next generation access nodes(NG-ANs) may terminate at the ANC. The ANC may include one or more TRPs308 (which may also be referred to as BSs, NR BSs, Node Bs, 5G NBs, APs,or some other term). As described above, a TRP may be usedinterchangeably with “cell.”

The TRPs 308 may be a distributed unit (DU). The TRPs may be connectedto one ANC (ANC 302) or more than one ANC (not illustrated). Forexample, for RAN sharing, radio as a service (RaaS), and servicespecific AND deployments, the TRP may be connected to more than one ANC.A TRP may include one or more antenna ports. The TRPs may be configuredto individually (e.g., dynamic selection) or jointly (e.g., jointtransmission) serve traffic to a UE.

The local architecture of the distributed RAN 300 may be used toillustrate fronthaul definition. The architecture may be defined thatsupport fronthauling solutions across different deployment types. Forexample, the architecture may be based on transmit network capabilities(e.g., bandwidth, latency, and/or jitter). The architecture may sharefeatures and/or components with LTE. According to aspects, the nextgeneration AN (NG-AN) 310 may support dual connectivity with NR. TheNG-AN may share a common fronthaul for LTE and NR.

The architecture may enable cooperation between and among TRPs 308. Forexample, cooperation may be preset within a TRP and/or across TRPs viathe ANC 302. According to aspects, no inter-TRP interface may beneeded/present.

According to aspects, a dynamic configuration of split logical functionsmay be present within the architecture of the distributed RAN 300. ThePDCP, RLC, MAC protocol may be adaptably placed at the ANC or TRP.

FIG. 4 illustrates an example physical architecture of a distributed RAN400, according to aspects of the present disclosure. A centralized corenetwork unit (C-CU) 402 may host core network functions. The C-CU may becentrally deployed. C-CU functionality may be offloaded (e.g., toadvanced wireless services (AWS)), in an effort to handle peak capacity.A centralized RAN unit (C-RU) 404 may host one or more ANC functions.Optionally, the C-RU may host core network functions locally. The C-RUmay have distributed deployment. The C-RU may be closer to the networkedge. A distributed unit (DU) 406 may host one or more TRPs. The DU maybe located at edges of the network with radio frequency (RF)functionality.

FIG. 5 is a diagram 500 showing an example of a DL-centric subframe. TheDL-centric subframe may include a control portion 502. The controlportion 502 may exist in the initial or beginning portion of theDL-centric subframe. The control portion 502 may include variousscheduling information and/or control information corresponding tovarious portions of the DL-centric subframe. In some configurations, thecontrol portion 502 may be a physical DL control channel (PDCCH), asindicated in FIG. 5. The DL-centric subframe may also include a DL dataportion 504. The DL data portion 504 may sometimes be referred to as thepayload of the DL-centric subframe. The DL data portion 504 may includethe communication resources utilized to communicate DL data from thescheduling entity (e.g., UE or BS) to the subordinate entity (e.g., UE).In some configurations, the DL data portion 504 may be a physical DLshared channel (PDSCH).

The DL-centric subframe may also include a common UL portion 506. Thecommon UL portion 506 may sometimes be referred to as an UL burst, acommon UL burst, and/or various other suitable terms. The common ULportion 506 may include feedback information corresponding to variousother portions of the DL-centric subframe. For example, the common ULportion 506 may include feedback information corresponding to thecontrol portion 502. Non-limiting examples of feedback information mayinclude an ACK signal, a NACK signal, a HARQ indicator, and/or variousother suitable types of information. The common UL portion 506 mayinclude additional or alternative information, such as informationpertaining to random access channel (RACH) procedures, schedulingrequests (SRs), and various other suitable types of information.

As illustrated in FIG. 5, the end of the DL data portion 504 may beseparated in time from the beginning of the common UL portion 506. Thistime separation may sometimes be referred to as a gap, a guard period, aguard interval, and/or various other suitable terms. This separationprovides time for the switch-over from DL communication (e.g., receptionoperation by the subordinate entity (e.g., UE)) to UL communication(e.g., transmission by the subordinate entity (e.g., UE)). One ofordinary skill in the art will understand that the foregoing is merelyone example of a DL-centric subframe and alternative structures havingsimilar features may exist without necessarily deviating from theaspects described herein.

FIG. 6 is a diagram 600 showing an example of an UL-centric subframe.The UL-centric subframe may include a control portion 602. The controlportion 602 may exist in the initial or beginning portion of theUL-centric subframe. The control portion 602 in FIG. 6 may be similar tothe control portion 502 described above with reference to FIG. 5. TheUL-centric subframe may also include an UL data portion 604. The UL dataportion 604 may sometimes be referred to as the pay load of theUL-centric subframe. The UL portion may refer to the communicationresources utilized to communicate UL data from the subordinate entity(e.g., UE) to the scheduling entity (e.g., UE or BS). In someconfigurations, the control portion 602 may be a physical DL controlchannel (PDCCH).

As illustrated in FIG. 6, the end of the control portion 602 may beseparated in time from the beginning of the UL data portion 604. Thistime separation may sometimes be referred to as a gap, guard period,guard interval, and/or various other suitable terms. This separationprovides time for the switch-over from DL communication (e.g., receptionoperation by the scheduling entity) to UL communication (e.g.,transmission by the scheduling entity). The UL-centric subframe may alsoinclude a common UL portion 606. The common UL portion 606 in FIG. 6 maybe similar to the common UL portion 506 described above with referenceto FIG. 5. The common UL portion 606 may additionally or alternativelyinclude information pertaining to channel quality indicator (CQI),sounding reference signals (SRSs), and various other suitable types ofinformation. One of ordinary skill in the art will understand that theforegoing is merely one example of an UL-centric subframe andalternative structures having similar features may exist withoutnecessarily deviating from the aspects described herein.

In some circumstances, two or more subordinate entities (e.g., UEs) maycommunicate with each other using sidelink signals. Real-worldapplications of such sidelink communications may include public safety,proximity services, UE-to-network relaying, vehicle-to-vehicle (V2V)communications, Internet of Everything (IoE) communications, IoTcommunications, mission-critical mesh, and/or various other suitableapplications. Generally, a sidelink signal may refer to a signalcommunicated from one subordinate entity (e.g., UE1) to anothersubordinate entity (e.g., UE2) without relaying that communicationthrough the scheduling entity (e.g., UE or BS), even though thescheduling entity may be utilized for scheduling and/or controlpurposes. In some examples, the sidelink signals may be communicatedusing a licensed spectrum (unlike wireless local area networks, whichtypically use an unlicensed spectrum).

FIG. 7 is a diagram 700 illustrating communication between the basestation 702 and the UE 704. The base station 702 communicates with theUE 704 according to a time structure defined by slots 712-0 to 712-5. Inparticular, the UE 704 may be scheduled to transmit one or more uplinkcontrol channels to the base station 702. An uplink control channel maybe a PUCCH and a PUSCH. In certain circumstances, at the UE 704, a firstuplink control channel is scheduled to be transmitted in a first slotset including multiple consecutive slots; a second uplink controlchannel is scheduled to be transmitted in a second slot set includingone or more consecutive slots. Further, the first uplink control channeland the second uplink control channel overlap in a first slot that isincluded in both the first slot set and the second slot set.

The UE 704 may determine that a particular uplink control channel of thefirst uplink control channel and the second uplink control channel is tobe transmitted in the overlapping slot (i.e., the first slot) based on apredetermined rule and that the other uplink control channel of thefirst uplink control channel and the second uplink control channel inthe overlapping slot is to be dropped. When an uplink control channel isscheduled in a slot and does not overlap with another uplink controlchannel, the UE 704 may transmit that uplink control channel in theslot. Again, the second slot set may have only one slot and the seconduplink control channel is scheduled to be transmitted in that one slot.

Each type of UCI is assigned a priority level. The UE 704 firstdetermines whether the UCI carried in the first uplink control channeland the UCI carried in the second uplink control channel have the samepriority level. When the respective priority levels of the UCI carriedin the first uplink control channel and the UCI carried in the seconduplink control channel in the first slot are the same, the UE 704determines that a slot set, of the first slot set and the second slotset, that starts prior to the other slot set is the slot set to betransmitted.

In one example, the UE 704 is scheduled to transmit an uplink controlchannel 742 carrying the same HARQ-ACK/NACK in each slot of a slot sethaving slots 712-0 to 712-3. Further, the UE 704 is scheduled totransmit an uplink control channel 744 carrying another sameHARQ-ACK/NACK in each slot of a slot set having slots 712-2 to 712-5.The uplink control channel 742 and the uplink control channel 744overlap in the slots 712-2 to 712-3. In other words, in the slots 712-2to 712-3, the UE 704 is scheduled to transmit both the uplink controlchannel 742 and the uplink control channel 744. Further, in each of theslots 712-2 to 712-3, the uplink control channel 742 and the uplinkcontrol channel 744 both occupy at least one common symbol period in theslot. The HARQ-ACK/NACK in the uplink control channel 742 and theHARQ-ACK/NACK in the uplink control channel 744 have the same prioritylevel. As the slot set having the slots 712-0 to 712-3 starts prior tothe slot set having slots 712-2 to 712-5, in the overlapping slots 712-2to 712-3, the UE 704 transmits the HARQ-ACK/NACK of the uplink controlchannel 742 and drops the HARQ-ACK/NACK of the uplink control channel744.

Further, the uplink control channels in the non-overlapping slots aretransmitted as scheduled. In this example, the HARQ-ACK/NACK in theuplink control channel 742 is transmitted in each of the slots 712-0 to712-1. The HARQ-ACK/NACK in the uplink control channel 744 istransmitted in each of the slots 712-4 to 712-5.

Further, when the UE 704 determines that UCI carried in a particularuplink control channel has a priority level higher than a priority levelof UCI carried in the other one of the first uplink control channel andthe second uplink control channel, the UE 704 transmits the particularuplink control channel in the overlapping slots. For example, thepredetermined rule may specify that a hybrid automatic repeat requestacknowledgement (HARQ-ACK) has a priority level higher than a prioritylevel of a scheduling request. A scheduling request has a priority levelhigher than a priority level of channel state information (CSI).Further, each type of CSI corresponds to a respective priority level.

FIG. 8 is a diagram 800 illustrating communication between the basestation 702 and the UE 704. The base station 702 communicates with theUE 704 according to a time structure defined by slots 812-0 to 812-4.

In one example, the UE 704 is scheduled to transmit an uplink controlchannel 842 carrying the same CSI in each slot of a slot set havingslots 812-0 to 812-3. Further, the UE 704 is scheduled to transmit anuplink control channel 844 carrying the same HARQ-ACK/NACK in each slotof a slot set having slots 812-3 to 812-4. The uplink control channel842 and the uplink control channel 844 overlap in the slot 812-3. Inother words, in the slot 812-3, the UE 704 is scheduled to transmit boththe uplink control channel 842 and the uplink control channel 844.Further, in the slot 812-3, the uplink control channel 842 and theuplink control channel 844 both occupy at least one common symbol periodin the slot. The CSI in the uplink control channel 842 has a prioritylevel lower than the priority level of the HARQ-ACK/NACK in the uplinkcontrol channel 844.

Therefore, in the overlapping slot 812-3, the UE 704 transmits theHARQ-ACK/NACK of the uplink control channel 844 and drops the CSI of theuplink control channel 842. Further, the uplink control channels in thenon-overlapping slots are transmitted as scheduled. In this example, theCSI in the uplink control channel 842 is transmitted in each of theslots 812-0 to 812-2. The HARQ-ACK/NACK in the uplink control channel844 is transmitted in the slot 812-4.

FIG. 9 is a diagram 900 illustrating communication between the basestation 702 and the UE 704. The base station 702 communicates with theUE 704 according to a time structure defined by slots 912-0 to 912-4.

In one example, the UE 704 is scheduled to transmit an uplink controlchannel 942 carrying the same CSI in each slot of a slot set havingslots 912-0 to 912-3. Further, the UE 704 is scheduled to transmit anuplink control channel 944 carrying the same HARQ-ACK/NACK in each slotof a slot set having slots 912-2 to 912-3. The UE 704 is also scheduledto transmit an uplink control channel 946 carrying the same schedulingrequest in each slot of a slot set having slots 912-3 to 912-4. Theuplink control channel 942 and the uplink control channel 944 overlap inthe slot 912-2. The uplink control channel 942, the uplink controlchannel 944, and the uplink control channel 946 overlap in the slot912-3. The CSI in the uplink control channel 942 has a priority levellower than the priority level of the scheduling request in the uplinkcontrol channel 946, which has a priority level lower than the prioritylevel of the HARQ-ACK/NACK in the uplink control channel 944. Therefore,in the overlapping slot 912-2, the UE 704 transmits the HARQ-ACK/NACK ofthe uplink control channel 944 and drops the CSI of the uplink controlchannel 942. Similarly, in the overlapping slot 912-3, the UE 704transmits the HARQ-ACK/NACK of the uplink control channel 944 and dropsthe CSI of the uplink control channel 942 as well as the schedulingrequest of the uplink control channel 946.

Further, the uplink control channels in the non-overlapping slots aretransmitted as scheduled. In this example, the CSI in the uplink controlchannel 942 is transmitted in each of the slots 912-0 to 912-1. Thescheduling request in the uplink control channel 946 is transmitted inthe slot 912-4.

FIG. 10 is a flow chart 1000 of a method (process) for transmittingmultiple multi-slot uplink control channels. The method may be performedby a UE (e.g., the UE 704, the apparatus 1102, and the apparatus 1102′).

At operation 1002, the UE determines that a first uplink control channelis scheduled to be transmitted in a first slot set including multipleconsecutive slots and that a second uplink control channel is scheduledto be transmitted in a second slot set including one or more consecutiveslots. At operation 1004, the UE determines that the first uplinkcontrol channel and the second uplink control channel overlap in a firstslot that is included in both the first slot set and the second slotset. At operation 1006, the UE determines that a particular uplinkcontrol channel of the first uplink control channel and the seconduplink control channel is to be transmitted in the first slot based on apredetermined rule.

In certain configurations, each type of uplink control information (UCI)corresponds to a respective priority level. In certain configurations, ahybrid automatic repeat request acknowledgement (HARQ-ACK) has apriority level higher than a priority level of a scheduling request. Incertain configurations, the scheduling request has a priority levelhigher than a priority level of channel state information (CSI). Incertain configurations, each type of CSI also corresponds to arespective priority level.

In certain circumstances, when determining that the particular uplinkcontrol channel is to be transmitted based on the predetermined rule, atoperation 1012, the UE determines that UCI carried in the particularuplink control channel has a priority level higher than a priority levelof UCI carried in the other one of the first uplink control channel andthe second uplink control channel. In certain circumstances, whendetermining that the particular uplink control channel is to betransmitted based on the predetermined rule, the UE, at operation 1022,determines that respective priority levels of UCI carried by the firstuplink control channel and the second uplink control channel in thefirst slot are the same. At operation 1024, the UE determines that aslot set, of the first slot set and the second slot set, carrying theparticular uplink control channel starts prior to the other slot set.

Subsequent to operation 1006, the UE, at operation 1008, transmits theparticular uplink control channel in the first slot and refrains fromtransmitting the other uplink control channel of the first uplinkcontrol channel and the second uplink control channel in the first slot.

FIG. 11 is a conceptual data flow diagram 1100 illustrating the dataflow between different components/means in an exemplary apparatus 1102.The apparatus 1102 may be a UE. The apparatus 1102 includes a receptioncomponent 1104, an uplink control channel component 1106, a prioritycomponent 1108, and a transmission component 1110.

The uplink control channel component 1106 determines that a first uplinkcontrol channel is scheduled to be transmitted in a first slot setincluding multiple consecutive slots and that a second uplink controlchannel is scheduled to be transmitted in a second slot set includingone or more consecutive slots. The uplink control channel component 1106determines that the first uplink control channel and the second uplinkcontrol channel overlap in a first slot that is included in both thefirst slot set and the second slot set. The uplink control channelcomponent 1106 determines that a particular uplink control channel ofthe first uplink control channel and the second uplink control channelis to be transmitted in the first slot based on a predetermined rule.

In certain configurations, each type of uplink control information (UCI)corresponds to a respective priority level. In certain configurations, ahybrid automatic repeat request acknowledgement (HARQ-ACK) has apriority level higher than a priority level of a scheduling request. Incertain configurations, the scheduling request has a priority levelhigher than a priority level of channel state information (CSI). Incertain configurations, each type of CSI corresponds to a respectivepriority level.

In certain circumstances, when determining that the particular uplinkcontrol channel is to be transmitted based on the predetermined rule,the priority component 1108 determines that UCI carried in theparticular uplink control channel has a priority level higher than apriority level of UCI carried in the other one of the first uplinkcontrol channel and the second uplink control channel. In certaincircumstances, when determining that the particular uplink controlchannel is to be transmitted based on the predetermined rule, thepriority component 1108 determines that respective priority levels ofUCI carried by the first uplink control channel and the second uplinkcontrol channel in the first slot are the same. The uplink controlchannel component 1106 determines that a slot set, of the first slot setand the second slot set, carrying the particular uplink control channelstarts prior to the other slot set.

The uplink control channel component 1106 transmits the particularuplink control channel in the first slot via the transmission component1110. The uplink control channel component 1106 refrains fromtransmitting the other uplink control channel of the first uplinkcontrol channel and the second uplink control channel in the first slot.
